'Horseback' in the Bible

So there went one on horseback to meet him, and said, "Thus says the king, 'Is it peace?'" Jehu said, "What do you have to do with peace? Fall in behind me!" The watchman said, "The messenger came to them, but he isn't coming back."

Then he sent out a second on horseback, who came to them, and said, "Thus says the king, 'Is it peace?'" Jehu answered, "What do you have to do with peace? Fall in behind me!"

Let the clothing and the horse be delivered to the hand of one of the king's most noble princes, that they may array the man whom the king delights to honor with them, and have him ride on horseback through the city square, and proclaim before him, 'Thus shall it be done to the man whom the king delights to honor!'"

He wrote in the name of King Ahasuerus, and sealed it with the king's ring, and sent letters by courier on horseback, riding on royal horses that were bread from swift steeds.
